The author examined computed tomographic (CT) scans of the chest from 40 patients with cultures positive for atypical mycobacteria. Common manifestations included bronchiectasis, air-space disease, nodules, and scarring and/or volume loss. ⋯ The anatomic distribution of the above findings was diffuse, not strongly favoring any lung zone. The identification of multifocal coexistent bronchiectasis, air-space disease, and nodules at CT should raise the possibility of atypical mycobacterial lung disease, even in an otherwise healthy patient.
